Van Gogh Wheatfield with Crows (Detail) July, 1890. This detail shows the remarkable rhythmic unity Van Gogh’s paintings had acheived in his later work. The shape of the crows is virtually identical to the top of sheaves of wheat. Using the same shape, but only in darkening shades of color, the gold of the wheatfields morphs into the black of the crows, making for a spectacular visual rhyme.
